MPEG stands for Motion Picture Experts Group. It's a standard for compressing video and audio. This page is only concerned with the audio part.
Browser requires some sort of MPEG-3 player application.
Configuring Netscape Navigator or Communicator:
The easiest way to set up Netscape to use your chosen MPEG player is to try clicking on a link to an MPEG file. If you don't yet have an MPEG player set up, a dialog box will pop up saying Nescape doesn't know how to handle a file of a given mime-type and asking what to do. Click on the Select App button select the MPEG player application from the folder in which it's installed.
If the dialog box described above doesn't come up, or if you want to change the MPEG player, you'll have to do it in the Preferences dialog:
- Select Preferences from the Edit menu and select the Applications tab/list item.
- Highlight the audio/mpeg or MPEG Audio item
- Click the Edit button.
- In the dialog that pops up, set that the type should be handled by an Application
- Choose your MPEG player using the Choose button.
- Repeat the process for the audio/x-mpeg mimetype.
- This is not as hard to do as it sounds here!
Configuring Internet Explorer:
- I'm going to have to admit I don't know exactly how this is done, but it's something like what you do with Netscape.
So far, there three layers (types) of MPEG audio encoding:
- layer 1 - roughly 2:1 compression, used in MiniDisc players
- layer 2 - up to 6:1 before you start to hear a difference
- layer 3 - at 11:1 (128Kbits/sec), most listeners will say it sounds like a CD.
- These days, layer 3 players are just as common as layer 2, so I recommend that you encode in layer 3.
You can convert to MPEG at one of several bitrates.
- I recommend 128Kbits/sec for stereo CD-quality material
- You could go down to 80Kbits/sec for mono.
- Try various bitrates to find the ideal quality/compactness tradeoff point for your music.
- At 32Kbits or below, I would recommend using Shockwave, since the quality will be the same or better and with Shockwave you'll get streaming.
You need an encoder application to convert your uncompressed AIFF/sdII/WAV files to MPEG.
Server does not require special software.
There's nothing other than the copyright law stopping the user from using MPEG audio data in whatever awful ways he/she wants.
